Strap for Flagship 38.5 Silver

The lug width of the Longines Flagship L4.874.4.72.2 is 20 mm. This dimension allows you to fit 20 mm straps, an extremely versatile standard with countless artisanal variants available. To verify it, measure the distance between the upper and lower attachment points of the case with a digital calliper, perpendicular to the lug shoulder.

The best strap depends on your usage and aesthetic preference. For the Flagship, glossy alligator in black or dark brown represents the most elegant choice, compatible with the case's classical proportions. Vegetable-tanned calf leather is ideal if you appreciate natural patina that ages beautifully; shell cordovan offers superior longevity. For sporty use, a 20 mm NATO or satin rubber in neutral tones preserves elegance without compromise.

To change the strap, you'll need a spring bar tool and a stable work surface. Place the watch on a soft cloth, locate the lugs (small metal levers hidden beneath the current strap), gently push them toward the centre with the tool to release the internal springs, and slide off the old strap. Repeat the process with the new strap, ensuring the springs lock securely.

Yes, the L4.874.4.72.2 is fully compatible with quality aftermarket straps, provided they respect the 20 mm lug width. MilanoStraps offers an extensive range of artisanal 20 mm straps customisable in leather (alligator, calf, shell cordovan), colours, initials and stitching thread, guaranteeing mechanical compatibility and construction quality superior to the market.

The lifespan of a leather strap depends on the material and usage. An alligator or vegetable-tanned calf strap, with regular maintenance (avoiding prolonged moisture, occasionally applying specific conditioner), typically lasts 5–8 years. Shell cordovan, thanks to its denser structure, can exceed 10 years. A sporty rubber strap lasts 8–12 years. The quality of the deployant significantly extends the overall life of the strap.
